I think the best tool for the “post e-mail era” is undoubtedly Diigo, which allows you to share sites you’ve bookmarked, with passages you find significant highlighted, and your own notes. You can also forward a link, with highlights and notes, to others by e-mail, if you prefer, or you can post all this information to your blog. And those are just the key points of what their integrated tools can help you do.
For two recent reviews that explain some of the power of Diigo, see: Under the Radar: Self Optimize and Adapt… and Intelligent Agent: Social Bookmarking for Enterprise Knowledge Management, which reviews several sites, including Diigo.
